Does Cas Latency Matter. Column Address Strobe (CAS) latency, or CL, is the delay time between the READ command and the moment data is available. Here's a good reference from the good people The general consensus is that memory timings and frequencies have marginal impact on real-world performance.
In asynchronous DRAM, the interval is specified in nanoseconds (absolute time). Find out more about CAS latency, RAM speed, and how to measure memory performance. If you have two different chips with different clock rates, and different latencies, that will complicate things.

What does RAM CAS latency mean?
How does it affect your speed? In synchronous DRAM, the interval is specified in clock cycles. It really isn't all that important.
